Workflow to convert dual arrival events into curtain plot section of formation slowness and logs of tool layer and shoulder bed slowness

Abstract

An automated workflow for processing dual arrival events consisting of: (1) an automated time pick that located and characterized dual compressional and shear arrival events present in acoustic waveform measurements; and (2) a ray tracing inversion procedure that inverted these time picks and constructed a locally layered formation model of slowness along the well trajectory. The disclosed workflow embodiments provide the following benefits: (1) an automated time pick which estimates the variation of the arrival event with measured depth and determines whether the shoulder bed is above or below the well track; and (2) a ray tracing inversion that determines the raypath type of the dual arrival event. The disclosed workflow embodiments provide a log display of tool layer and shoulder bed compressional and shear slowness which is useful for making correct porosity, VP/VS, and Poisson ratio estimates as well as other geomechanics answers.
